Answer:
Independent variable - vitamin gro and exercise routine.
Dependent variable - growth of children or nieces.
Explanation:
There are two variables present in an experiment called dependent and independent variables.
Independent variables are those variables which can be controlled in an experiment and dependent variables are those variables which are measured in the experiment under the influence of the independent variable.
In the given experiment, the independent variable will be vitamin gro and exercise routine and the dependent variable is the growth of children or nieces because vitamin gro and exercise routine can be controlled and growth of children is dependent on vitamin gro and exercise routine.
Most organisms rely on the sun as a primary source of energy
The answer is A.
You can remember this by thinking that since there was no change in the amino acid sequence, the mutation is silent in the fact that it didn't cause any trouble in the amino acid sequence.
Loss of biodiversity matters because it affects the overall sustainability of organisms in an ecosystem. It also affects how badly an ecosystem will be affected after something, maybe a natural disaster, or maybe a disease, strikes the region. (For example, if a disease affects a certain species of organism, if there was a lot of biodiversity among individuals, some will have some kind of natural immunity to that disease and survive, passing on their favorable traits to the next generation. However, if everybody was the same and did not have the immunity to that disease, that entire population would eventually die out.) <- This is also the reason that lack of biodiversity will inhibit natural selection.
Hope that helped you.
